A 19-year-old man was arrested Saturday on suspicion of second-degree murder and driving under the influence after he crashed his car in South San Francisco late Friday, resulting in the deaths of his two passengers, authorities said.

An 18-year-old woman from San Francisco and a 21-year-old man from Brisbane died in the crash, according to police. Both were thrown from the 1994 Honda Civic that Joshua Matthew Maldonado was driving after he shaved another car on Airport Boulevard at Pine Avenue and then struck a tree alongside the road, police said.

The victims’ names were not immediately released, pending notification of their families.

Maldonado was briefly hospitalized for non-life-threatening injuries before being taken into custody by police. Investigators said he appeared to have been drinking alcohol and was driving close to 90 mph in a 35 mph zone before grazing the other car shortly before midnight.
